将选项卡更改为XML文件中的空格

Question

在创建了许多文件后，我将Eclipse配置更改为use spaces instead of tabs。它起作用：我写的新东西使用空格。但是我昨天写的文件当然还有标签。我想将从标签转换为空格。

对于Java文件很简单：打开文件，按CTRL + a，按CTRL + i，完成。

但如何对XML文件执行 ？与Java不同，使用XML文件CTRL + a / CTRL + i不仅可以转换标签，还可以尝试“改进格式化”，这会破坏事物：

初始代码：

<?xml version='1.0' encoding='UTF-8'?>

    <bean id="webscript.helloworld.get"
          class="com.example.HelloWorldWebScript"
          parent="webscript">
    </bean>
</beans>

CTRL + a / CTRL + i（或CTRL + SHIFT + f）后：

<?xml version='1.0' encoding='UTF-8'?>

问题：对于Eclipse中的XML文件，如何将制表符转换为空格而不进行其他更改？

Answer 1

好吧，如果您是手动操作，并且不想要自动脚本，只需在XML文件中写一个标签，然后复制它，然后按ctrl + f＆gt;更换，粘贴标签以找到替换的内容和空间，然后只需更换全部。如果您不想用脚本替换它，那就是这样。

Answer 2

Search - ＆gt; Search...（或 Ctrl + H ） - ＆gt; File Search，

检查Regular expression，

将\t设为Containing text:，

将*.xml设为File name patterns，

点击Replace...，设置 （根据需要添加空格） - ＆gt; OK。

完成。请享用。

Answer 3

您的方式正确，但首先，您必须自定义XML格式：

• 打开Window > Preferences > XML > XML files > Editor。
• 选中format comments并取消选中Join lines。 （这应该缩进注释并删除相邻的空格，因此，保留现有的换行符。但如果您对结果感到不舒服，请取消选中format comments。）
• 选择Indent using spaces并设置indentation size。

现在，您可以按[SHIFT][CTRL][F]格式化XML文件。
